如何将smarty变量传递给php函数？

PHP CODE:

function show_playlist_form($array)
{
    global $cbvid;
    assign('params',$array);

    $playlists = $cbvid->action->get_channel_playlists($array);
    assign('playlists',$playlists);

    Template('blocks/playlist_form.html');
}

HTML CODE (SMARTY INSIDE): 

<html><head></head>
<body>
{show_playlist_form}
</body>
</html>

This all can be found in clip-bucket video script. The html code calls the php function, where it shows playlist_form.html. However, I'm interested in adding an integer value in the smarty defined tag show_playlist_form so that it would pass it to the function in php show_playlist_form($array) and then the function would assign the integer into $array.

I tried, assuming I'm interested in passing the integer 1:

{show_playlist_form(1)}

Fatal error: Smarty error: [in /home/george/public_html/styles/george/layout/view_channel.html line 4]: syntax error: unrecognized tag: show_playlist_form(1) (Template_Compiler.class.php, line 447) in /home/george/public_html/includes/templatelib/Template.class.php on line 1095

{show_playlist_form array='1'}

The html code worked but it I got nothing (blank).

So, it didn't work, what can I do? I need to pass integer values to the function.

    What you are looking for here is to implement a "custom template function" which receives parameters.

    As shown in the documentation on function plugins, the function you create will receive two parameters:

    • an associative array of named parameters from the Smarty tag
    • an object representing the current template (useful for e.g. assigning additional Smarty variables)

    So for instance, if you define this:

    function test_smarty_function($params, $smarty) {
      return $params['some_parameter'], ' and ', $params['another_parameter'];
}

    And register it with Smarty under the name test like this:

    $template->registerPlugin('function', 'test', 'test_smarty_function');

    Then you could use it in your templates like this:

    {test some_parameter=hello another_parameter=goodbye}

    Which should output this:

    hello and goodbye

    In your case, you probably want something like this:

    function show_playlist_form($params, $smarty) {
     $playlist_id = $params['id'];
     // do stuff...
}

    and this:

    {show_playlist_form id=42}
